Describe the bug
HiddenSwitch [X] can not be triggered by side blocks since 1.15.

To Reproduce

1. CraftBook/mechanisms.yml : HiddenSwitch.any-side: true
2. Create a Hidden Switch with [x] sign and lever.
3. Test correct behaviour by clicking the block where the sign is attached to.
4. Click on a block attached to a side of the [x] sign. => The lever will not trigger.

I cannot reproduce this issue, it's working fine for me?

Originally, the button has been triggered when clicking on each of the green blocks. Now, it's only the sign-block which works.

That's incorrect behaviour - Due to a Spigot bug I had to temporarily remove the check that prevented that from working, but the bug was later fixed so the check was able to be re-added.

OkayI did'nt know that. Thanks for your help!
